This repository hosts the content and static site generator for nginx.org.

The website is primarily authored in XML and converted to static HTML content through Extensible Stylesheet Language Transformations (XSLT).

The .xslt files in this repo are automatically generated and should not be edited directly. XML transformation is defined by .xsls files and performed by XSLScript as part of the site generation process.

The XML content is then combined with the corresponding XSLT file(s) that generates HTML in the libxslt directory.

    end

Site generation is performed with make(1) with several targets, notably:

• The default target creates the static HTML (this is usually enough for local development).
• images target creates thumbnail icons from sources for the books page.
• gzip target creates compressed versions of the HTML and text content which is used by the production website.

Use the Dockerfile to create a self-container Docker image that approximates the production website.

docker build --no-cache -t nginx.org:my_build .

The docker image exposes port 8080 as per the convention for container hosting services.

The static site generator uses a UNIX/Linux toolchain that includes:

• make
• perl
• xsltproc
• xmllint - typically found in the libxml2 or libxml2-utils packages
• jpegtopnm, pamscale and pnmtojpeg - typically found in the netpbm package; only required for the images make(1) target
• rsync - only required for the gzip make(1) target

macOS ships with all of the above with the exception of the netpbm tools. This can be installed with Homebrew if required.

Some Linux distros may also require the perl-dev or perl-utils package.

Windows TODO

With the prerequisites installed, run make from the top-level directory. This will create the libxslt directory with HTML content therein.

1. Build the site

make

2. Start a local web server configured to serve the site.

docker compose up -d

3. Test the site by visiting localhost:8001.

TODO

Existing pages are edited by modifying the content in the xml directory. After making changes, run make from the top-level directory to regenerate the HTML.

New pages should be created in the most appropriate location within a language directory, typically xml/en. The GNUmakefile must then be updated to reference the new page before to included it in the site generation process.

After determining the most appropriate location for the page, choose the most appropriate Document Type Definition (DTD) for your content. This will determine the page layout and the XML tags that are available for markup. The most likely candidates are:

• article.dtd - for general content
• module.dtd - for nginx reference documentation

Note that DTD files may include other DTDs, e.g. article.dtd includes content.dtd.

Pay attention to existing files before making significant edits. The basic rules for XML content are:

• Lines are typically no longer than 70 characters, with an absolute maximum of 80 characters.
• Each new sentence begins on a new line.
